摘要： A method of regulating the tension of warp yarns in a weaving machine is disclosed herein. Displacement of a tension roller, which is movable with a change in warp yarn tension, from a reference position corresponding to an optimum tension of the warp yarns in the weaving machine is detected by a sensor, which then converts such mechanical displacement of the tension roller into electrical signals proportional to the amount of said displacement. The signals are sampled successively in synchronism with the operation of the weaving machine. Adjustment of the speed at which a warp beam is rotated is made depending upon the data from sampled signals in such a way that the speed is decreased when the tension is dropped beyond the lower limit of a predetermined range, while it is increased when the tension is built up to exceed the upper limit thereof. In addition, adjustment of the warp beam rotational speed is made such that the speed is increased when the tension is built up so rapidly within the range as to exceed a predetermined rate, while it is decreased when the tension is dropped so rapidly within the range as to exceed said rate.

摘要： A weft yarn guide of an air jet loom comprises a base portion capable of being connected to a sley, a pair of guide members which are connected to the upper end of the base portion and which are forked to form a weft inserting opening therebetween, a base fluid passage formed within the base portion, and a plurality of fluid blowing holes formed on the upper portions of the guide members and communicated with the base fluid passage. The weft yarn guide further comprises a branching wall projected from the upper inner wall of the base fluid passage in order to branch air flow fed from the base passage into two flows, and a pair of branch passages formed within the guide members in order to communicate the base fluid passage with the fluid blowing holes, whereby the air flow is smoothly branched without causing substantial turbulence.
